Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

Embodiment 1, referring to Fig. 1 and Fig. 2, and the rotating mechanism of band damping; Comprise two rotating components 1,2; Rotating component 1 comprises a substrate 11, and the bottom that substrate 11 both sides are provided with two first stringer board 12, the first stringer boards 12 vertical with substrate 11 forms through hole 121; Through hole 121 on two first stringer boards 12 is coaxial, forms the through hole 111 that is used to connect parts such as cursor on the substrate 11.Rotating component 2 comprises two separate " L " shape plates 21; " L " shape plate 21 comprises a substrate 211 that is used to connect parts such as cursor and perpendicular to second stringer board 212 of substrate 211; Second stringer board, 212 tops form through hole 2a, and bolt 31 passes after through hole 121 and the through hole 2a and nut 32 is threaded through what match.The lower end of first stringer board 12 is provided with the lug boss 123,124 that stretches out along through hole 121 radially outwards.

Referring to Fig. 3, the rear side of " L " shape plate 21 forms the lug boss 213 that stretches out laterally.

Referring to Fig. 4, when rotating component 1 relatively rotates part 2 when turning to several angle, lug boss 123,124 and lug boss 213 lean, and limit rotation part 1 is rotated further.

Referring to Fig. 2, bolt 31 passes second stringer board 212, wear-resistant sleeve 4, first stringer board 12, wear washer 5, isolation pad 6 and resilient pad 7 backs successively and nut 32 is threaded through what match.One end of bolt 31 is a damp block 311, forms groove 312 on the damp block 311, and groove 312 is as the accommodating part.With form projection 2b on the damp block 311 contacted rotating components 2, projection 2b snaps in the groove 312.Screw rod 313 partial sidewall of bolt 31 are processed with a plane 314.Wear-resistant sleeve 4 is processed for polyformaldehyde material, has good wear resistance and self lubricity.Wear-resistant sleeve 4 is made up of two-part, and one is the pad 41 between first stringer board 12 and second stringer board 212, is used to the frictionally damage that prevents that first stringer board 12 and second stringer board 212 from producing when rotating each other; Another piece causes damage to bolt 31 when being used to prevent 12 rotations of first stringer board between bolt 31 and through hole 121.Through hole 61 tops in the middle of the isolation pad 6 also are plane 6a, and separator 6 is enclosed within 31 last times of bolt, and plane 6a and plane 314 contact, and prevent that separator 6 relative bolts 31 from rotating.Be provided with wear washer 5 between the isolation pad 6 and first stringer board 12, wear washer 5 polyformaldehyde materials are processed, and have good wear resistance and self lubricity, are used to prevent produce frictional loss between first stringer board 12 and the isolation pad.Resilient pad 7 is arranged between nut 32 and the isolation pad as elastic component.
